Hair with low or poor elasticity is often described as brittle and prone to breaking easily. Elasticity in hair refers to its ability to stretch and return to its original shape without breaking. When hair lacks elasticity, it means it does not have the flexibility to withstand tension or stretching without sustaining damage. This condition can be caused by factors such as excessive heat styling, chemical processing, or lack of moisture, leading the hair to become rigid and fragile.

In contrast, the other descriptions do not relate to low elasticity. For instance, soft and pliable hair indicates good elasticity, while silky and smooth hair suggests healthy texture and moisture balance. Oily and heavy hair also does not reflect issues with elasticity but rather pertains to the scalp's sebum production. Therefore, brittle and breaking easily is the characteristic that accurately describes hair with low or poor elasticity.
